Oooh, an experiment. Cool. I like those! I've spent quite a bit of time storing and incubating old eggs, and manage to get quite good results from eggs that are three weeks old, when just about everyone on here says 7-10 days max.
Please report back on your results when you've run a couple of incubations.
You could always think about sitting your eggs in egg cartons, and tipping the bator side to side?
I never thought about just tipping the bator... wow... great idea!!!
